Numerous error messages when model does not balance

Good Luck :-0)
Version 6.0.3.18
I opened Antarctic model (any should work)
-run in ecosim
-run fishing policy search (just to replicate)
-edit groups: add a group
-there were at least 10 pop-up screens to tell me my model was no longer balanced
I think one for every ecosim screen I had open :-)
Good lord, it took me 5 minutes to get out of that mess!!!

Ok the errors are not so bad, as long as you are not in an active Ecosim interface. If you run ecosim and go to Basic input and then try to add a group you dont get as many errors as if you were in the run ecosim interface and then just click edit groups.

So I know it is not the smartest to edit groups from an ecosim interface, but just thought I would let you know.

The core asserts when trying to re-run Ecopath after adding or removing groups. An Ecopath run is very likely to fail, the core should not throw an assertion but should exit gracefully.

After removing the assert a few errors pop up which make sense but should somehow be averted. Perhaps a change could be to stop the core from reloading Ecosim whenever Ecopath has been restructured, etc.

Implemented this: when restructuring a level (Ecopath < Ecosim < Ecospace), levels above the restructured level are no longer automatically reloaded since the altered level needs to be re-assessed and will probably not run correctly.
